Is there a report that shows the tax and N.I deductions for maternity pay including forcasting future months?

It's nice to see you in this forum, @Lisa303. We can run the Payroll Detail report, which contains information about your payroll transaction for each employee. I'm here to assist you with this.

This report offers a detailed overview of your employees' earnings, deductions, taxes, and other payroll-related information for a specific period. However, please know that it won't generate your future months data, as payroll hasn't been processed for those periods. 

As a workaround, you can consider exporting this report, then manually add and calculate the deductions for your workers future months. To do so, here's how:

1. Open your QuickBooks Online account. 
2. Go to Reports, search for Payroll Detail using the search field provided.
3. Click the Export dropdown, then select Export to Excel.
4. Once done, open the downloaded file. 
5. Afterward, add and edit the necessary information from Excel. 

Additionally, I'll include these articles you can check out to learn more about managing your payroll effectively:
